JOHN W. THOMAS, OF CHICAGO, ILLINOIS, ASSIGNOR TO THE THOMAS RAILWAY TRACK APPLIANCE COMPANY, A CORPORATION OF KANSAS.

RAIL-SECURING DEVICE.

Application filed November 19, 1915.

To all whom it may cmwern:

Be it known that I, JOHN W. THOMAS, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Bail-Securing Devices, of which the following is a specification.

My invention relates to improvements in railway track appliances, and my object is to provide new and useful means for re liably securing rails from tipping laterally and creeping longitudinally.

In the accompanying drawing which illustrates the invention:

Figure 1 is a cross section of a rail held in position by my appliances.

Fig. 2 is a plan view of the invention with the rail removed.

Fig. 3 is a section on line III of Fig. 1.

Fig. 4: is a broken section on line IVIV of Fig. 2, with a spike and part of a rail base added.

Fig. 5 is a detail of an important element of the invention.

Fig. 6 is a broken detail of a spike.

A designates a rail, and B a cross-tie of any ordinary or preferred construction.

1 designates a tie-plate provided near one side with a lip 2 adapted to overlap the ad jacent flange of the rail base C. Said lip 2 is reinforced with a series of transverse arched portions 3, reinforced with ribs 3 and having comparatively sharp corners A adapted to bite the rail and assist in securing the same from creeping longitudinally.

5 designates an abutment integral with the tie-plate and spaced from the lip 2 to admit the base C of the rail, as disclosed by Fig. l. Said abutment 5 is interrupted near its ends with segmental bosses 7 having threaded holes 8 to receive rail-securing members 9.

Each member 9 comprises a circular portion 10, an angular head 11 surmounting said circular portion to receive a wrench, a shank having a threaded cylindrical portion 12 to engage the threads in the holes 8, and a wedge shaped lower terminal 13 adapted to be embedded in the cross-tie B to prevent the member 9 accidentally unscrewing from the tie-plate 1.

One margin of the spike hole 6 has an upwardly extending lug 14 with a sloping side 15 to force the head of a spike D firmly against the adjacent margin of the rail base.

Specification of Letters Patent.

Patented May 29, 1917.

Serial No. 62,386.

In practice, one side of the base flange G is slipped under the lip 2, after which the members 9 are screwed into the holes 8 until the circular portions 10 firmly bear upon the underlying rail base and firmly force the same into its seat on the tie-plate 1. The tops of the members 9 are then tapped with a maul to force the terminals 13 into the underlying crosstie B, until the tie-plate 1 is brought down squarely into engagement with the upper surface of said cross-tie B. The spikes D are then driven into the cross-tie B through the openings provided in the tieplate 1. As the spike D at the right is driven home its heel (Z contacts the sloping side 15 of the lug 14 and forces the spike firmly against the rail base, the heel d at the same time becoming firmly wedged against the lug 14 and the head of the spike, thereby reliably securing the spike against accidental withdrawal.

From the foregoing arrangement, it is obvious that the rail will be firmly held upon 'thetie-plate 1 through the intermediacy of the lip 2 and the members 9, and after the latter have been forced into the cross-tie B, they cannot rotate and release their grip on the rail. It will also be noted that the spike engaging the lug 14. will be securely held from accidental withdrawal.

While I have shown and described the preferred combination, arrangement, and construction of parts, I reserve the right to make such changes as fall within the spirit and scope of the claims.

Having thus described my invention, what I claim and desire to secure by Letters Patent, is:

1. In a device of the character described,

a tie-plate having a threaded hole therein, 9

and a rail securing member consisting of a rail-engaging portion, a threaded portlon depending from said rail-engaging portion and adapted to be screwed into the threaded hole of the tieplate, and another portion depending from said threaded portion and adapted to be embedded in a cross-tie to pre vent rotation of said rail securing member.

2. In a device of the character described, a tie-plate having a threaded hole therein. and a rail securing member consisting of a wide portion to overlap an adjacent portion of a rail, a threaded portion depending from said wide portion and adapted to be screwed into said threaded hole, and a wedge-shaped portion depending from said threaded portion and adapted to be embedded in a cross-tie to prevent rotation of said rail securing member.

3. In a device of the character described, a tie-plate having a threaded hole in one side and a rail engaging member at its opposite side, and a rail securing member consisting of a wide portion to engage an adjacent portion of a rail, a Wrench-receiving portion surmounting said Wide portion, a threaded portion depending from said wide portion and adapted to be screwed into the threaded hole of the tie-plate, and a shank depending from said threaded portion and adapted to be embedded in a cross-tie, for the purpose set forth.

4. A rail securing member comprising a circular portion, a rectangular portion surmounting said circular portion, a threaded portion depending from said circular portion and a chisel-shaped portion depending from said threaded portion.

In testimony whereof I affix my signature in the presence of two Witnesses.

JOHN W. THOMAS.
